RE:
Bethel Road I
ST 99-05
Pacheco Koch / Duke Construction Drainage Request
Dear Mr. Bond:
The city has reviewed your letter dated September 13, 2005 regarding Duke Construction's
request to discharge storm water from the parking lot of two proposed buildings into the
currently designed drainage system for Bethel Road. Your findings indicate that the
proposed storm water discharge can be accommodated through the upsizing of Line D and
that the 25-year capacity of the four 10' x 5' box culverts is sufficient to handle the
additional flows.
The city has no objections to TranSystems upsizing Line D to accommodate the storm
drain water from the proposed development. It is understood that Duke Construction is
responsible for TranSystem's engineering costs associated with the upsizing of Line D and
for all revisions to the Bethel Road I construction plans related to proposed development.
The city will need to review the revisions prior to the plans being finalized.
Should you have any questions or need any additional information, please advise.
Sincerely,
Kenneth M. Griffin, P.E.
